光纖收發器主要分為兩種:

1.單纖收發器是通過一芯光纖傳輸,使用波分復用技術,將兩束不同波長的光信號在一根光纖傳輸,從而實現同時發送和接收。

2.雙纖收發器有兩個口,且都是發射一樣的波長,因此接線時採用平行的兩根光纖交叉連接。

如何區分單纖收發器與雙纖收發器

a.當光纖收發器內嵌光模塊時,可通過鏈接的光纖跳線的纖芯數量區分。

b.當光纖收發器沒有內嵌光模塊時,可根據插入的光模塊接口區分。

Fiber Transceiver Type

There are two main types of fiber optic transceivers:

1.Single-fiber transceiver is transmitted through a core optical fiber. Using wavelength division multiplexing technology, two beams of optical signals with different wavelengths are transmitted on one optical fiber, so as to achieve simultaneous transmission and reception.

2. The dual-fiber transceiver has two ports, and both emit the same wavelength, so two parallel optical fibers are used for cross connection when wiring.

How to distinguish single fiber transceiver from dual fiber transceiver

a. When the optical transceiver has an embedded optical module, it can be distinguished by the number of cores of the linked fiber jumper.

b. When the optical transceiver does not have an embedded optical module, it can be distinguished according to the interface of the inserted optical module.
